I really have to say that I'm surprised how much control over the household an 8 week pup has gained within the (has to be) short time he's been with this family.

I'm wondering how long he's been in the house. I thought most puppies were homed around 8 weeks old...am I mistaken?
-- and determining "Alpha/Beta" designations between owners so soon?????

I just keep shaking my head in disbelief. I could be very much mistaken, but I find this a bit much for a very young puppy to already have accomplished :( :(
"Losing Trust" within this short of a time span by a primary handler (your husband) is not good. If he can't trust your dog at this stage, he likely never will. :( Your 10 year old daughter should not be disciplining him either. It is not a child's job and can easily be mishandled by one so young.
Seriously, if you are not confident about what is happening and this puppy is this much out of control, please consider returning him to the breeder. He has a good chance of gaining a household that is better suited to his nature and (very new) habits while he is a young puppy. Huskies are not for everyone. They require much dedication. You said his parents were "Not particularly calm"...well, if both were like this, it's highly likely his nature will reflect their traits.
If you decide to keep your puppy, please consult with the breeder and look for a Husky fancier's club in your region. They will be able to help you out with the training of your dog.
